Flotation is an effective gold recovery process. Gold concentrate grade and gold recovery rate are the key output indicators of the flotation process.
The flotation process is a widely used method for separating minerals from their ores. It relies on the differences in surface properties of the minerals to be separated. Here are the steps involved in the flotation process: Grinding: The ore is first crushed into a fine powder through the process of grinding.
Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 ...

Gold carbon-in-pulp (CIP) is a typical gold beneficiation process for the effective recovery of gold-bearing minerals with a high oxidation degree and low grade of raw ore. Gold CIP has become a widely used gold extraction method worldwide because of its advantages of high adsorption rate, high recovery rate, and low investment cost.

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
